[PEG-TEA]LP, as a new biodegradable ionic liquid catalyst, was successfully synthesized, characterized, and applied to the one-pot pseudo-five-component synthesis of bis(pyrazolyl)methanes.
Dibenzo[b,h][1,6]naphthyridines were synthesized in one pot by reacting 2-acetylamainobnezaldehyde with methyl ketones under basic conditions, methylation of which showed strong fluorescence.
